Biodegradation of total petroleum hydrocarbon from Al-Daura refinery wastewater by Rhizobacteria

Abstract EN

Due to the deliberate disposal of industrial waste, a great amount of petroleum hydrocarbons pollute the soil and aquatic environments.

Bioremediation that depends on the microorganisms in the removal of pollutants is more efficient and cost-effective technology.

In this study, five rhizobacteria were isolated from Phragmites australis roots and exposed to real wastewater from Al-Daura refinery with 70 mg/L total petroleum hydrocarbons (TPH) concentration.

The five selected rhizobacteria were examined in a biodegradation test for seven days to remove TPH.

The results showed that 80% TPH degradation as the maximum value by Sphingomonas Paucimobilis as identified with Vitek® 2 Compact (France).
